First, test with a person who has a single preferred language.

>>> setUp()
>>> provideUtility(DummyLanguageSet(), ILanguageSet)
>>> provideUtility(
...     DummyLaunchBag('foo.bar@canonical.com', dummyPerson), ILaunchBag)
>>> provideAdapter(
...     adaptRequestToLanguages, (IBrowserRequest,),
...     IRequestPreferredLanguages)
>>> provideAdapter(
...     adaptRequestToLanguages, (IBrowserRequest,),
...     IRequestLocalLanguages)

>>> languages = preferred_or_request_languages(DummyRequest())
>>> len(languages)
1
>>> languages[0].code
'es'

>>> tearDown()

Then test with a person who has no preferred language.

>>> setUp()
>>> provideUtility(DummyLanguageSet(), ILanguageSet)
>>> provideUtility(
...     DummyLaunchBag('foo.bar@canonical.com', dummyNoLanguagePerson),
...     ILaunchBag)
>>> provideAdapter(
...     adaptRequestToLanguages, (IBrowserRequest,),
...     IRequestPreferredLanguages)
>>> provideAdapter(
...     adaptRequestToLanguages, (IBrowserRequest,),
...     IRequestLocalLanguages)

>>> languages = preferred_or_request_languages(DummyRequest())
>>> len(languages)
6
>>> languages[0].code
'ja'

>>> tearDown()

>>> from lp.services.worlddata.helpers import is_english_variant
>>> class Language:
...     def __init__(self, code):
...         self.code = code
>>> is_english_variant(Language('fr'))
False
>>> is_english_variant(Language('en'))
False
>>> is_english_variant(Language('en_CA'))
True
>>> is_english_variant(Language('enm'))
